DEVICE FOR PURIFYING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 232,822, dated October 5, 1880.

Application filed April 10, 1880. (N o model.) i

Zo all whom it may concern:

Be it known that I, ANDREW C. HUMPHREYs, of the city of Urbana, in the county of Champaign and State of Ohio, have invented certain new and useful Improvements in Devices for Purifying Liquids, of which the following is a specification.

. The object of my invention is the providence of cheap, convenient, and effectual means whereby liquids can be cleaned from sediment and otherimpurities hel d therein bysuspen sion.

The nature of my invention will be fully apparent from the following description.

Among the various instances in which my improvements can be applied is that known as the driven well,77 and inasmuch as the mode in which my invention operates with a driven well is a good illustration of how it operates in every instance, I have shown my invention as applied to and operatin g in connection with such a well.

In the accompanying drawings, making a part of this specification, Figure 1 is a view, in perspective, ofthe exterior ofa device embodying my invention. Fig. 2 shows a vertical central section of the same, taken through outlet 2 and pipe B of Fig. 1, and also showing, by dotted lines, a pump attached to the upper end thereof. i

A indicates the entire device, and B represents the inlet-pipe through which the liquid to be cleansed enters the receiver C. For the sake of compactness this inlet-pipe B is so curved near and at its inlet-orifice that the latter shall be directly below the bottom of the receiver and shall terminate in an end to which the vertical pipe or conduit of a driven well may at pleasure be conveniently attached in any of the customary and well-known modes of connecting the ends of pipes or tubing. In cases where the pipe or conduit supplying the liquid is horizontal, or in a direction other than vertical, the direction of the end of pipe B must be changed to meet and make a proper connection with the supply-pipe.

rIhe pipe B discharges into the receivei1 C at the upper part of the latter,`as shown, so as to allow room in the receiver below the point of its discharge intothe latter for sediment, Ste., t0 collect without clogging itsdischarge-aperv IThe pipe B is further provided, near its point 5 5 of discharge into the receiver, with an elbow,

F, and, the direction of the latter being nearly horizontal, causes thel discharge of liquid from pipe B into the receiver to be in a horizontal direction, thereby the better enabling the weight 6o ofthe impurities, sediment, 85e., in the liquid to assist in causing the impurities to settle to the bottom of the receiver. In other words, the impulsion impa 'ied to said impurities by the current of liqu. through the pipe B does not operate to force this sediment, &c., up into the outlet-pipe of the receiver, but allows the force of gravity to feely act in drawing them to the bottom of t J receiver.

For the purposes of more effectually pre- 7o venting any ot the impurities circulating in the receiver from being carried up into the outlet-orifice H of the receiver, a wire screen, I, is placed across the upper portion of the receiver, and this screen catches the impurities, e., and pre 'ents them passing through into saidoutlet-oriiice H, and when the liquid is quite full of impurities a second screen, J, is placed in the receiver and at a short distance from andin front of the discharge-ori- 8o lice E of pipe B, so as to check the passage of the impurities toward the outlet H, and for the better enabling the screen J to deflect the upward course of the impurities, and to allow the latter an opportunity to fall without ad- 85 hering to the screen J, the latter is inclined from a point at the side of the receiver some little distance above the discharge-oridceE of pipe B, in a downward direction, diagonal to the length of the receiver and toward the cen- 9o ter of the latter. (See Fig. 2.)

For convenience of construction and of attachment of the screens I and J, the receiver is constructed in two parts-viz., a main portion, A,and a cap,L, arranged to be connected in any suitable manner. One mode is that shown-viz., the main portion Kand cap L are provided with outwardlyextending flanges connected together by bolts N. Between the faces of the cap L and the main portion K the Ico edges of the screens are located, and the screens themselves are thus firmly held in position; but any other desirable mode of attaching the screens to the receiver may be employed. The upper end of the cap L, containing the orifice H, is to be formed so as to be suitably secured in any of the well-known methods to the outlet-tube or conduit above it. In the present instance the lower end of pump l? (shown in dotted lines in Fig. 2) is screwed into the upper end of cap L.

Ihe sand or other sediment collecting in the bottom of the receiver must, at suitable intervals, be removed, and for this purpose there is provided the sediment-outlet Q, located substantially as shown, so as to enable the sediment collecting at the bottom of the receiver to be most conveniently discharged. This outlet Q is closed by a suitable device-in the present instance by a screwplug, It, screwed into the receiver, so as to close the said orifice. The screw-plu g Ris provided with a square head, so that by the application ot' a wrench it may be screwed into or out of the orifice Q.

To'facilitate the removal of the sediment, Ste., collected at the bottom of the receiver C, the bottom of the latter is preferably made to slant from the side of the receiver opposite to where the orifice Q is located downwardly to the said orifice. The weight of the sediment, 85e., will thus aid in its removal. The pipe or conduit B is made or east in one piece with the receiver or portion K thereof.

When my invention is employed to separate sand, Ste., from the water or oil of a driven well the device A is usually placed just below the pump and above the tubing of the well, and is connected to both pump and tublng.

The mode in which my invention operates is as follows :,The liquid enters the pipe B at D, and is discharged at E. Where device Fig. 2 is employed the liquid strikes against screen J, which collects the impurities circulating in the liquid, and allows the same to fall to the bottom ot' the receiver. The liquid passes on, mostly through the screen J and up to screen I, which also stops such impurities which have got from under screen J and been carried up to screen I, and prevents their ingress into oriiice H and the pump I). The liquid is thereby delivered free oi' sediment, and the valves ot' the pump are prevented from being cut, Worn, or clogged by sediment or other impurities.

My invention is of great value in clearing the running waters of springs. Where, however, the low of liquid through the receiver is intermittent, as is usually the case when a pump is employed, the sediment, Snc., circulating in the water has a better opportunity ot' settling to the bottom.

When the receiver has become quite full of sediment, 85e., the plug B is withdrawn and the sediment removed through orifice Q. The

liquid in the receiver, in its endeavor to pass out of said orifice, will aid in removing said sediment, Ste., and where the receiver is provided with a slanting bottom, W, gravity will aid in removing the said sediment.

Where the supply of liquid to the receiver is continuous, as in the case ot' a spring, the pressure and iiow of liquid to the receiver will very rapidly carry the sediment, Svc., through the oritice Q.
